Abstract: Varicose veins are a prevalent vascular disorder caused by weakened vein walls and malfunctioning valves, resulting in improper blood circulation and vein enlargement in the lower extremities. Early identification and timely intervention are essential to prevent complications such as venous ulcers and chronic discomfort. This paper presents a wearable healthcare system designed to detect and manage varicose vein conditions using a concurrent sensor network integrated with a heat treatment module. The proposed system employs multiple sensors, including photoplethysmography (PPG), temperature, infrared, and pressure sensors, to acquire physiological data related to blood circulation and skin temperature variations. The collected signals are processed using a microcontroller-based system that performs real-time analysis and identifies abnormal vascular patterns. Upon detecting irregularities, the system activates a controlled heat therapy module to improve blood flow and reduce discomfort. The integration of sensing and therapeutic functionality enables continuous monitoring and immediate intervention, enhancing patient convenience and reducing dependency on hospital visits. The proposed framework demonstrates the effectiveness of IoT-based wearable systems in improving vascular health monitoring and providing automated therapeutic response for varicose vein management.
